As previously described the water jacke formed between the inner and outer walls Y 8 and 9 of the furnace constitutes a boiler.

kzo

' The boiler 9 is in communication with the radiator ll'through theV pipe connections 15 and 16 and therefore the heated waterwill circulate through theV system.

The outer wall of the boiler ofthe radiator 11 are corrugatedin order to increase as much as possible the radiating surface. Y

The'action of the system asrregards the delivery ofy heated air is identical with the ordinary pipeless hot air furnace the pasf sage of air through the 'system being indicatedA by Ythearrows in Fig.'1. f f y i 'The entire radiating surface of the boiler and radiator 11 is in contact with the air inside the inner shell 17 so that this air becomes heated 'and rises, being l,delivered through the register 19. Y

' The cold lair Vdescends through the register 22 downwardlythrough the annular chamber 23 and into the bottom open endV of the innershell 17 Ywhere it again contacts with 'Y the radiating surface, becoming heated thereby and passes up again through the Y re ister 19. Y

y the provision of the corrugated walls 9, 13 and 14: the radiating surface in contact Y with the air within the inner shell 17 is increased to Vamaxiinum and therefore the economy ofthe system is increased. Y

It will be notedY that the inner and outer shells 17 and 20 constitute a tubular 'casing within which the boiler andradiator ele-Y ments are situated.

yBetween thewalls 17 and 20 of the tubu-VY lar casing is Vformed'the annular chamber 23, the'uppernend of which communicates with the cold air register 22'and thelower end of which communicates AWith the lowerv open Vend of the shell 17 while-theV upper endy of the shell 17V communicates with the municates with theY bottom of hot air register 19. It will thus be apparent lthat'the annular chamber y23 constitutes a down flow passage for cool'air whichA com,-

anY up flow 4ifraeea f or steam through pipes to radiators at various points within the building to be heated, whereas in my system it is the object to increase to a maximum the radiationY from .the outer wallY of the 'boiler and vto veffect the heating of the building by the delivery ofV air which has been heated by contact withv this radiating surface, thus eliminating the use of expensive fixtures including pipes Y and radiators located throughout the Abuilding." V- Hitherto, in pipel'ess hot air furnaces the air is heated vby'cont'a'ct with the extremely hot radiating surface of the furnace fand is thus rendered VextremelyV dry before delivery to the building..` l This is oneof the great disadvantages of hot"Y air systems and the fact that Yafmuch more temperate'heating may be obtained Vby the use of hotv water heating accounts for the greaterY popularity :of hotwater overr 1n my ksystem however the hot air does.V Y notcome in contact with the hotV furnace plates but insteadV engages the radiating sur-l face of the boiler and radiator. elements Ywhich arev not heated above`1212 F..

Therefore all the advantgesvofthe hotY Yreferred tofvare retained in my system.

iHitherto the high costof hotwater and. steam systems, dueto expensive fixtures' throughout the buildingl has militatedV Y against their universal use andsince these are entirely eliminated in mysystema` it will be evident thatvthe advantages of the hot water and steam systems are'reta'ined while the disadvantages of the hot air system are eliminated.
